Australian top order batsman Shaun Marsh was unable to fulfill a media engagement ahead of the third test against India in Perth because of illness on Monday. Team officials said the 28-year-old should be fit to train with the rest of the team on Tuesday ahead of Friday’s start to the test at the WACA. Marsh won a race to be fit for the first test but his form in the four-match series has been far from convincing, despite Australia making a strong start with emphatic wins in Melbourne and Sydney. Playing at number three in the batting order, Marsh has been out for a duck twice and made three in the second innings at the Melbourne Cricket Ground. Mike Hussey, who bucked his own run of poor form with a superb 150 not out in Sydney, replaced Marsh in Monday’s news conference and backed his fellow Western Australian to find his touch at his home ground.
